inflection x^4-6x^3

Solution

inflection points

x^{4} - 6 x^{3}

Solution

(0, 0), (3, - 81)

Solution steps

f^{''} (x) = 12 x^{2} - 36 x

Find intervals:

Concave Upward

: - \infty < x < 0,

Concave Downward

: 0 < x < 3,

Concave Upward

: 3 < x < \infty

Plug

x = 0

into

x^{4} - 6 x^{3} : 0

(0, 0)

Plug

x = 3

into

x^{4} - 6 x^{3} : - 81

(3, - 81)

(0, 0), (3, - 81)
